1, first check whether the charging cable jack problem, if no problem, see the next step.
2, again check whether there is dust in the type-c interface on the phone, if there is the problem.

First find the card needle or sewing needle that comes with the phone, and then gently swipe the card against the quasi-interface hole until the dust is clean.

1, charger aging, short circuit.
2, chargers shoddy products (with poor quality components), small horse-drawn carts (small power used in high power), it will generate large heat.
